A CORPORATION OF NEW YORK BUILDING CONSTRUCTION Application filed July 23,

. This invention relates to building constructions and particularly to constructions of the type wherein channels or chases are provided in thewalls adjacent the floor levers for the reception of service pipes or conduits and/ or the reception of the edges of floor slabs.

In building constructions heretofore known, the principal expedients for concealing the service lines, such as plumbing pipes, electric conduits and the like were: to conceal them in a trench in the floors adjacent the walls; or in a floor fill between the floor slab and the finished floor; or in the ceiling of the next lower story; or to conceal them in a chase in the wall, formed by corbelling out of .masonry immediately above the chase or by using a steel plate to support the masonry about the chase.

The disadvantages of the first three expedients were: that the service lines were inaccessible for repairs and changes; thefloors and ceilings were subject to cracking, resulting from expansion and contraction of the pipes; the floors and ceilings were subject to damage from possible leakage of the pipes;

and the floors were weakened because of the reduced amount of structural material. In the case of concealment of the service lines in chases in the walls, additional labor was necessary in setting the masonry; the wall section was reduced, and consequently its structural strength and moisture-excluding property were reduced; and where a steel plate was used, additional expense for material was entailed.

In the prior wall and floor constructions, the walls were built up to each floor level and then the floor slab was poured, after which the walls were extended up to the next floor level and so on. It was thus necessary to suspend the construction of the walls at each floor level until the floor slab had set which delayed the completion of the structure and necessitated a greater expense than would I have been necessary had it been possible to continue the erection of the walls without interruption.

'An object of the invention is the provision I in a wall construction, of chases or channels 1n the wall for the reception of service hues 1931. Serial No. 552,723.

and/or the reception of floor slabs, wherein the chased portions of the walls will have the 7 same structural strength and the same moisture-excluding properties as the other por from expansion or contraction of the pipes or leakage therefrom, and wherein easy access may be had to the service lines for the purpose of making repairs or alterations.

Other objects will'appear from the following description and the accompanying drawing,wherein Fig. 1' is a perspective view partially in cross-section showing a portion of a wall constructed according to the invention, and v V Fig. 2 is a similar view showing a fioor slab and service lines intheir proper places.

According to the present invention, a horizontal recess 1 is provided in the wall2, at the floorlevel, and arow of channel-shaped, ce-

ment blocks 3 are set: into the recess 1 with g the webs innermost and the flanges extending to, and terminating flush with the inside face of the wall todefine a chase or channel 4: ex-

tending horizontally along the inner side of the wall 2. When the structural floor slab 5 is poured, the flanged edge portion 6 is formed in situ within thechase thus constituted, whereby the floor slab 5 is securely supported by thewall 2. A finish coating 7 of fine concrete or other suitable plastic material is poured on the floor slab 5 after the same has set to provide a smooth hard finish for the floor.

Also disposed in 1 second chase 9 .are disposed the horizontal the recess 1 in the wall 2, immediately above the row of blocks 3, 9

til

service lines 10, 11, such as plumbing pipes, electric conductor conduits and the like. The open side of the chase 9 preferably is closed by expanded metal lathing 12 which supports a plaster wall section 13 constituting the floor board. This section may, if preferred, be formed, for example, of metal, wood, or tabricated material. The fioor board is provided with outlet openings 14, 15 for the pipes 10 and'wi'res 11.

The channel-shaped block 3 and 4 is "pre'ferably formed of a mixture of cement, annaterial rich in aluminosilica compounds such as sand, blast furnace slagand wa-ter'molded as a relatively dry mix under heavy pressure and subsequently steam cured, as is more fully set forth in the copending application of Rowland McVVilliams, Serial No. 318,- 010, filed November 8, 1928. The size *and composition of the finished block-are such that the block has as great structural strength as, and-even greater moisture-excluding ability than the section of masonry which it replaces.

It will be seen that the present invention provides -a wall having provision for receiving the edges of floor slabsand for concealing service lines, which wall issimple and inexpensive to erect, which has as great me chanical strength and greater moisture-ex- "eluding ability than an all masonry wall, and which wall may be com-pletely'erected beforeth'e floor slabs are Ip'ouredor the serv- "i'ce-linesinstalled. It also'should be'noted "that in the present construction, the same type of labor may be employed i n placing' the c "the masonry wall, whereas in the construction fo'rm thechannel, a difierenttype of inner face of said wall.
